10 developments

Kolkata: Trinamool Congress councillor Mohmmad Iqbal, who is an accused in the murder case of a Kolkata policeman, has been arrested from Bihar. The policeman, Sub Inspector Tapas Chaudhuri, was shot dead during clashes between Congress and Trinamool workers at a college in Kolkata on February 12.

Here are 10 developments in the case:

"Iqbal has been arrested from Dehri-on-Son. He will be brought to Kolkata," said Shibaji Ghosh, Additional Director General, CID. He will be produced before a Kolkata court where the CID will seek his transit remand from the court, added Mr Ghosh.

Mr Iqbal is charged with rioting, attempt to murder and certain sections of the Arms Act by police. The CID, which subsequently took over the investigation, had been looking for Mr Iqbal for almost a month.

Video footage aired by television channels showed Mr Iqbal standing next to a man called Sheikh Shubhaan when the latter fired the bullet that the police say killed the Sub Inspector. Mr Shubhaan was among 12 people who were arrested within two days of the violence.

The violence in the college erupted over the issue of picking up nomination forms for the students' union election. The cop was shot dead while trying to break up the clashes.

Two days after the clash, West Bengal Chief Minister Mamata Banerjee removed Kolkata's police chief RK Pachanda and said she was angry that people named in the FIR had not been arrested.

Ms Banerjee's detractors had alleged that Mr Pachanda was removed as Commissioner because he wanted to arrest some members of her party in connection with the policeman's death. Mr Iqbal is known to be close to the state's Urban Development Minister Firhad Hakim, who in turn is close to the Chief Minister.
